摘要
分析了现有桩筏基础在沉降计算理论上的缺憾,提出以剪切位移协调法计算桩土的相对滑移,给出了桩土相对滑移量的计算公式和考虑相对滑移的桩基沉降计算方法。通过与工程实测的比较,本文提出的方法能达到工程要求的精度。
Settlement calculation defects of pile raft foundation are analysed in the paper. Transference of load shearing displacement method is presented to calculate the relative slipping between piles and soil. Calculation formula of the relative slipping between piles and soil are given, the settlement calculation of pile foundation considering the relative slipping between piles and soil is putforward. Through the comparison with the engineering example, the method given in the paper can achieve the required accuracy.
